Capture

Remarque

La capture Firewire - au minimum - a été enlevée durant le portage vers KDE 5 en raison du manque de main-d'œuvre.

Kdenlive fournit une fonctionnalité permettant de capturer la la vidéo à partir de dispositifs externes; par exemple, Firewire, FFmpeg, Screen Grab et Blackmagic.

Vous configurez la capture vidéo via Configuration -> Configurer Kdenlive -> Capture (informations supplémentaires sur ce sujet ici).

You define the destination location for your captures by using Settings -> Configure Kdenlive -> Environment -> Default Folders (more on this here).

Pour faire une capture vidéo, sélectionnez le moniteur d'enregistrement et choisissez le périphérique de capture de la liste déroulante, en bas à droite.

Firewire

This captures video from sources connected via a firewire (also known as - IEEE 1394 High Speed Serial Bus) card and cable. This functionality uses the dvgrab program and the settings for this can be customized by clicking the spanner icon or choosing Settings>Configure Kdenlive. See Configure Firewire Capture.

Pour réaliser une capture:

Plug in your device to the firewire card and turn it on to play mode
Click the Connect Button
Click the Record Button — note it toggles to grey while you are recording
Click the Record button again to stop capture. Or click the stop button.
Once capturing is finished, click the disconnect button
In the Captured Files dialog, click the import button to have the captured files automatically imported into the project tree.

Note: If your device does not start playing the source device when you click the record button, you may have to start playback on your device manually and then click record.

FFmpeg

Je pense que cette capture vidéo depuis une WebCam utilise Video4Linux2.

Screen Grab

This captures video of the PC screen. In version 0.9.2 it uses recordMyDesktop to do the capture. There is an open defect with this functionality in ver 0.9.2 — See bug tracker ID 2643.

In version 0.9.3, the screen grab is done by the ffmpeg functionality instead. For screen capture to work in ver 0.9.3, the version of ffmpeg installed needs to have been compiled with the --enable-x11grab option. Ubuntu comes with an ffmpeg version compiled with this option.

To check on your linux distro, type ffmpeg -version in a terminal and look for --enable-x11grab in the reported configuration info. ^[1]

If you are capturing the screen and using the X246 with audio settings and you get a crash as shown in the screen shot ...

... then consider creating a profile for audio capture where -acodec pcm_s16le is replaced by -acodec libvorbis -b 320k. See Configure Kdenlive.

Blackmagic

Ceci est pour capturer à partir de cartes de capture vidéo Blackmagics decklink (autant que l'on sache). Incertitude concernant la stabilité du code. Voir le défaut 2130.

Notes

↑ There are now two branches of ffmpeg: a Libav branch and an ffmpeg.org branch. The ffmpeg version from the latter branch reports the configuration when you run with ffmpeg -version. The Libav version does not. So this method to check for the --enable-x11grab does not work if you have the Libav version of ffmpeg.
